Abstract (en)
[origin: US4384136A] Amino acid fractions of different composition are obtained at different times by fractional filtration after neutralization of the hydrolysates. Tyrosine-rich and leucine-rich fractions are specifically treated and lead to the recovery of L-tyrosine, L-cystine, L-leucine and L-phenyl-alanine.
